This should give you Intel graphics output. Note that this requires kernel 3.5rc1 or higher; use linux-mainline from Aur if necessary. See [https://bugzilla.kernel.org/show_bug.cgi?id=42842 this bug] for more details.

If you don't have KMS for intel driver, you need install {{Pkg|xf86-video-fbdev}} and, of course {{Pkg|xf86-video-intel}}.

+

+

If Xorg refuses to start with a "no screens found" message you may have to tell Grub2 to turn off the Radeon card and turn on the Intel card during boot. Edit /etc/grub.d/00_header and add the "outb" lines immediately after "set gfxmode=" (Tested on an 8,2 MBP):

+

+

...

+

set gfxmode=${GRUB_GFXMODE}

+

outb 0x728 1

+

outb 0x710 2

+

outb 0x740 2

+

outb 0x750 0

There are two drivers to provide features to the touchpad (including right and middle click): [https://github.com/BlueDragonX/xf86-input-mtrack mtrack] which is reported to work well and [[Synaptics]] which provides more features but might require some tuning.

To enable most of the multitouch touchpad features (even right and middle clik) use [https://github.com/BlueDragonX/xf86-input-mtrack mtrack], which is avaible in [https://aur.archlinux.org/packages.php?ID=48505 AUR]. The configuration is done via the /etc/X11/xorg.conf.d/10-mtrack.conf file. Check if the mtrack module is properly loaded in the /var/log/Xorg.0.log file. Sometimes xorg loads other drivers before, like eg. synpatics, and the mtrack driver is not used at all.

For an MBP 8,3 I needed to use the following config (in /etc/X11/xorg.conf.d/10-mtrack.conf) to stop it picking up other input devices by mistake:

Using [[PulseAudio]] sound works out of the box. However some applications (e.g. [[Vlc]]) have intermittent crackling; appending 'tsched=0' to 'module-udev-detect' in /etc/pulse/default.pa fixes this.

As noted elsewhere in this document, some MBP features work best (or only) with the latest kernel; the usual way to install this is using the [https://aur.archlinux.org/packages.php?ID=50893 linux-mainline] AUR package. However, as of 3.6.rc3 the config for linux-mainline disables webcam support (due to changed defaults in kernel). [http://pastebin.com/WbYpPrg1 This patch] to the x86_64 config fixes this issue.

Which means you need disable KMS for amd and intel card. Add following to Kernel Parameters.

i915.modeset=0 radeon.modeset=0

newer versions of the Xorg Intel/i915 driver require KMS to work; without it the X server will fallback to framebuffer mode, with poor performance. The underlying issue is that the Intel KMS driver selects the wrong video output; to fix this try the following settings (tested on an 8,3/17" MBP):

radeon.modeset=0 i915.modeset=1 i915.lvds_channel_mode=2

This should give you Intel graphics output. Note that this requires kernel 3.5rc1 or higher; use linux-mainline from AUR if necessary. See this bug for more details.

Troubleshooting

Grub2-EFI boot: Intel invalid ROM contents

If you see this error on boot and notice the screen output seemingly frozen, you need to disable KMS.

Append the following to your /etc/grub/defaults LINUX line:

i915.modeset=0 radeon.modeset=0

However, newer versions of the Xorg Intel/i915 driver require KMS to work; without it the X server will fallback to framebuffer mode, with poor performance. The underlying issue is that the Intel KMS driver selects the wrong video output; to fix this try the following settings (tested on an 8,3/17" MBP):

radeon.modeset=0 i915.modeset=1 i915.lvds_channel_mode=2

This should give you Intel graphics output. Note that this requires kernel 3.5rc1 or higher; use linux-mainline from Aur if necessary. See this bug for more details.

You may find you need to enable the Intel device; if using Grub, the following should enable it at boot time:
